c# - fill grid view from textbox and dropddown list values recursively on each button click -

I want to fill the grid view with the text box and dropdown list values ​​with the button click. Currently it is only binding once. New to ASP.NET Support will be highly appreciated

  Protected Zero BTNED_click (Object Sender, EventEurges E) {DataTable DT = New DataTable (); Datarov Dr; Dt.Columns.Add ("Resources"); Dt.Columns.Add ("Available"); (Int intCnt = 0; intCnt & lt; grd.rows.Count - 1; intCnt ++) {if (grd.Rows [intCnt] .write type == DataControlRowType.DataRow) {dr = dt.NewRow (); [["Resource"] = grd.rows [intCnt] [0]; Dr. ["Available"] = grd.rows [intCnt] [1]; Dt.Rows.Add (Dr.); }} Dr = dt.NewRow (); Dr. ["Resource"] = ddlResource.SelectedItem.Text; Dr. ["available"] = txtavailable.Text; Dt.Rows.Add (Dr.); Grd.DataSource = dt; Grd.DataBind ();  

Please try it out to see if it will help
